背景技术 Background technique
目前,常用的黑板擦基本上有毛刷型和毛毡型两种形式,均运用滑动摩擦原理除去黑板粉笔字迹。毛刷、毛毡等材料对粉尘有较好的吸附作用,当毛刷型或毛毡型黑板擦表面比较洁净时,它具有较好的擦拭效果,也不易产生粉尘,但是任何材料的吸附作用都是有限度的,毛毡也不例外,因此,当毛刷型或毛毡型黑板擦使用了一段时间后,其表面吸附一层厚厚的粉笔灰,此时,如果继续用它来擦拭黑板,不仅不能把黑板擦拭干净,而且同样会使粉笔灰尘四处飞扬、污染空气、损害人体健康。 At present, conventional blackboard erasers basically have two types of brush type and felt type, and all use the principle of sliding friction to remove chalk writing on the blackboard. Materials such as brushes and felts have a good adsorption effect on dust. When the surface of the brush type or felt type blackboard eraser is relatively clean, it has a good wiping effect and is not easy to generate dust, but the adsorption effect of any material is There is a limit, and felt is no exception. Therefore, when the brush type or felt type blackboard eraser has been used for a period of time, a thick layer of chalk dust is adsorbed on its surface. At this time, if you continue to use it to wipe the blackboard, not only cannot Wipe the blackboard clean, and it will also cause chalk dust to fly around, pollute the air, and damage human health.

所述的擦拭板两端滑动连接导杆,导杆安装在上盒体上的开口两端。 The two ends of the wiping plate are slidably connected to the guide rods, and the guide rods are installed at both ends of the opening on the upper box body.
所述的风机与设置在下盒体内的电池盒连接,并通过设置在下盒体外壁上的开关控制。 The fan is connected to the battery box set in the lower box body, and is controlled by a switch set on the outer wall of the lower box body.
所述的过滤网为柔性纤维过滤网,具有较好的吸附作用,而且方便清理。 The filter is a flexible fiber filter, which has good adsorption and is easy to clean.
由于采用上述技术方案,本实用新型的优点在于:本实用新型在黑板擦的上盒体上预留有吸层缝,在左右擦拭黑板的时候,吸层缝总是处于粉尘掉落的一侧,而掉落的粉尘由于风机的倒吸作用,通过吸层缝全部被吸附到过滤网上,从而实现无尘操作。当过滤网粉尘过多的时候,可以将上盒体与下盒体翻开,将附着过滤网上的粉尘抖落下来,方便下一次使用。因此,本实用新型不仅结构简单,使用方便,实现达到“无尘”擦拭的效果,避免粉笔灰尘四处飞扬、污染空气、损害人体健康。 Due to the adoption of the above technical solution, the utility model has the advantages that: the utility model reserves a suction layer seam on the upper box body of the blackboard eraser, and when wiping the blackboard left and right, the suction layer seam is always on the side where the dust falls , and the falling dust is all absorbed to the filter net through the suction layer seam due to the suction effect of the fan, so as to realize dust-free operation. When there is too much dust on the filter screen, the upper box body and the lower box body can be opened to shake off the dust attached to the filter screen, which is convenient for the next use. Therefore, the utility model is not only simple in structure, but also convenient to use, and realizes the effect of "dust-free" wiping, avoiding chalk dust flying around, polluting the air, and damaging human health.

具体实施方式 Detailed ways
为了使本实用新型目的、技术方案和优点更加清楚,下面结合附图和实施例对本实用新型作进一步的详细说明。 In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.
实施例 Example
吸尘黑板擦的结构示意图如图1所示,包括相互连通的上盒体3和下盒体5,所述的上盒体3与下盒体5采用合页4活动连接,在上盒体3顶部设置有开口10,在开口10内滑动连接有擦拭板1,所述的擦拭板1与开口10侧壁之间预留有吸层缝12,在下盒体5顶部设置有分隔上盒体3与下盒体5内部空间的过滤网11,所述的过滤网11为柔性纤维过滤网,在过滤网11下方的排风口9处设置有风机8。所述的擦拭板1两端滑动连接导杆2,导杆2安装在上盒体3上的开口10两端。所述的风机8与设置在下盒体5内的电池盒7连接,并通过设置在下盒体5外壁上的开关6控制。因此,在左右擦拭黑板的时候,吸层缝12总是处于粉尘掉落的一侧,而掉落的粉尘由于风机8的倒吸作用,通过吸层缝12全部被吸附到过滤网11上,从而实现无尘操作。当过滤网11粉尘过多的时候,可以将上盒体3与下盒体5翻开,将附着过滤网11上的粉尘抖落下来,方便下一次使用。 The schematic diagram of the structure of the dust-absorbing blackboard eraser is shown in Figure 1, including an upper box body 3 and a lower box body 5 that are connected to each other. The upper box body 3 and the lower box body 5 are flexibly connected by hinges 4. 3 There is an opening 10 on the top, and a wiping plate 1 is slidably connected in the opening 10. A suction layer seam 12 is reserved between the wiping plate 1 and the side wall of the opening 10, and a separate upper box body is arranged on the top of the lower box body 5. 3 and the filter screen 11 in the inner space of the lower box body 5, the filter screen 11 is a flexible fiber filter screen, and a fan 8 is arranged at the air outlet 9 below the filter screen 11. Both ends of the wiping plate 1 are slidably connected to guide rods 2 , and the guide rods 2 are installed at both ends of the opening 10 on the upper box body 3 . The fan 8 is connected with the battery box 7 arranged in the lower box body 5 and controlled by the switch 6 arranged on the outer wall of the lower box body 5 . Therefore, when wiping the blackboard left and right, the suction layer slit 12 is always on the side where the dust falls, and the dropped dust is all absorbed onto the filter screen 11 by the suction layer slit 12 due to the suction effect of the blower fan 8. This enables dust-free operation. When the filter screen 11 has too much dust, the upper box body 3 and the lower box body 5 can be opened, and the dust attached to the filter screen 11 can be shaken off, which is convenient for next use.
